T0 ALL WHOM '.['.l.v MAY CONCERN: t u

Be it known that l', PIERRE Mi C, BZIEL, of Paris, in the Empireof.-F-rance, have invented a new and useful` Improvementjn theManufacture of Chains, Bracelets, and other articles of jewelry; and Ido hereby `declare that the following is a Vfull and exact descriptionthereof.

Thisinvention has for its object certain improvements in the manufactureoffchains, bracelets, necklaces,

i' and other articles of jewelry. Iii-may also be applied with advantageinall cases where delicatenietal ornaments are required. This' willreadily be understood from the following description of rny modeof'proce'eding. 'Having engraved a. suitable designV in two hollow diesor moulds, corresponding one with the other, and whose edges areproperly lformed to cut out the edges'and openings of the patterns, Itake a sheet o'ffdopper, or other equivalent malleable metal, soluble inacids, and place it ybetween two sheets of gold, whose` thickness, asalso thatof the copper, is' determined'by the nature of the article'oiiwhich it is to form` part. .The three sheets `thus arranged Aaire placedAe een the dies, to which pressure is gradually applied until-they meet,and the -design',thus,cut out formed. Tllcpiecc. is .then-withdrawn,and.the.roughwedgesmootlxeddowneby suitable"V instruments until ithusattained 'a suiiicicnt degree of finish. IV must here observe thatwhen chains, bracelets,

. I eolrlccaror-sixnilar articles are to bemanut'aetured, thcldesignmust be fof such a nature as will admit ofthe piece or linkformed inlthe moulds being readily and-elegantly joined by solder or otherwise toa similarpicce.

i Whenjthe article is so completed, the chain, 'or whatever it may be,is,` subjected `to ainitrie acid'batli,",which y.dissolves out thecopper, leaving the gold intact. .In-some cases it may be desirable tohave a half-design; by this I mean oneluncomplemented by its fellow. Insuch a case I make useof one sheet of gold and one of cop-` per,`treating"them, however, as before, except that one die only is sunk,the only dili'erence being, in one case y'the model has a solid*appearance, in the other the model'is in relief only on one side. Thechief feature of my invention, therefore, consists in ystamping orcutting out, and forming by pressure iusuitable dies, `with the `aid ofV a relief Vplateof malleablemetal soluble iuacidor otherwise, thelinks, leaves, or 'other models suitable for ,manufacture into` chains,bracelets, and all `such similar articles, whether'for u'se or ornament.In some cases, and for a particular class' of ornament, I make use of awire of copper, or other equivalent malleable metal soluble by acid, inplace of the sheetof'copper before alluded. to. This I coverwith goldleaf, the copper being employdsimply `to give suicient solidity to admitofthe gold leaf bearingthe pressure 'towliich't is subjected indeed vanyform to suit the purpose and ornamenttobe manufactured therefrom, and`may be either retainedfin ,its casing ofgold, or be dissolved out by`nit-ric acid. In this latter case small holes are made'in the goldcasing .to 'allbwthe acid to reach the copper.

Having thus fully described my invention, I claim as new,` and desire`to secure by'Letters Patentha The method, substantially as herein setforth, fof forming links, leaves, or other similar articles, `of gold orsilver, for ornamental or useil purposes. a v i i f Initestmony whereofI have hereunto set my nainefin the presence'of twosubscribin'gwitnesses.`
